It's in "intuition/classes.h" (declared as 'typedef struct IClass {...}
Class' AFAIRC).
intuition/classusr.h is also an interesting include for BOOPSI class
writers.

You receive an object and a class pointer in your dispatcher, these can
be used to get the instance data of the object by using the
INST_DATA(cl, obj)-macro.
Gadget data belonging to your superclass should normally be accessed by
invoking Get- & SetAttrs() on your own object, but if you want to be
dirty then I think the object pointer passed to your gadget is
equivalent with the Gadget pointer (if your object is a Gadget) -- The
includes should mention more about this, I haven't tried to make use of
this fact myself...
